Who cares who created the content?
Sure, the person who wrote, recorded, or produced it cares. And probably, their parents do, too (if my personal experience is any indicator.)
And maybe, if the person is a known expert or celebrity in their field, the publisher cares because their involvement will draw more attention.
But for most, authorship doesn’t matter. Yet, given the voluminous conversations around generative content AI, you would think it does.
